Theoretical Perspectives The importance of paradigms 1. It is necessary to have a paradigm in order to guide the questions that are asked--otherwise, research & conceptualization of problems would be aimless. 2) It is important to be aware of the assumptions or beliefs that are implicit to the paradigm. 3) It is important to be aware of other available paradigms-other possible explanations.

Sullivan) Object Relations Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Key Freudian Concepts: Psychic determinism; the role of unconscious conflicts Personality is a closed energy system Sexuality, aggression and other instinctual drives shape the nature of personality Personality has 3 major components (id, ego and superego) Defense mechanisms Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Dimensions of the Mind: Freud Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Key Freudian Concepts: Psychosexual stages of development model oral stage (birth to 1 year) anal stage (1 to 3 years) phallic stage (3 to 6 years)--Oedipal & Electra complexes latency stage (6 to 12 years) genital (adolescence to adulthood) Fixation; the importance of early development Psychoanalysis - the talking cure (free association, dream analysis, interpretation, analysis of defenses, interpretation of transference).

Sullivan) Object Relations School (Heinz Kohut) Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Behavioral models Classical Conditioning (I. Pavlov) Operant Conditioning The Law of Effect (Thorndike) Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Classical Conditioning Step 1: Unconditioned stimulus (UCS) > Unconditioned response (UCR) Conditioned Stimulus (CS) Step 2: Pairing UCS and CS > No response Conditioned Response (CR) + Step 3: Conditioned Stimulus (CS) > Conditioned Response (CR) Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Operant Conditioning Positive reinforcement- increasing a behavior by providing a positive reinforcer when the behavior occurs Negative reinforcement- increasing a behavior by removing a negative reinforcer when the behavior occurs Punishment- decreasing a behavior by providing a negative reinforcer when the behavior occurs Extinction (omission training)- decreasing a behavior by removing a positive reinforcer when the behavior occurs Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Operant Conditioning Other concepts: - Shaping - Schedules of reinforcement - Primary and secondary reinforcers Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Recent variations of behavioral theory Social learning theory Delay of reinforcement Social modeling Cognitive- behavioral theory Information processing models of abnormal behavior Cognitive restructuring of mis-perceptions Irrational and Core beliefs Abnormal Psychology, 11/e by Sarason & Sarason © 2005 The Humanistic/ Existential or “3rd force” in psychotherapy Reacted against the determinism of psychoanalysis and behavior therapy (Carl Rogers) Focus is on conscious experiences, trying to understand the person from his/her frame of reference. Positive opinion about human nature--basically good, & if conditions are right, will grow & develop. Emphasis is on health, self-concept, self-actualization-humans have an inborn need for growth. Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Abraham Maslow’s Hierarchy of Needs Self-actualization Esteem Needs Belongingness Needs Safety Needs Physiological Needs Abnormal Psychology, 11/e by Sarason & Sarason © 2005 Client-centered therapy (C. Rogers) Major techniques: 1. Empathic listening/ unconditional positive regard 2. Reflection of content 3. Reflection of intent/ feeling Abnormal Psychology, 11/e by Sarason & Sarason © 2005 The Community-Cultural Perspective 1. Recognizes the importance of the context of problems-poverty, homelessness, lack of education or personal resources, stigma & labeling, etc. 2. Maladaptive behavior is seen as a result of the inability to cope with external demands or stresses. 3. Recognizes role of families and social support in either increasing or reducing risk of mental disorder. Abnormal Psychology, 11/e by Sarason & Sarason © 2005
